MIXING APPARATUS.

Application led May 29,

j My invention relates to a mixing apparas tus, the main object being to provide a simple, inexpensive and efiicient mixing appara-l tus capable ofbeing associated withV kegs, barrels, caslrs and similar liquid holding vessels for mixing paints and other materials and ingredients. @ne of the objects of my invention is to provide a mixing apparatus having support inthe form of a lid or cover furnished with lmeans whereby to be fitted 'to different sizes of kegs, barrels and other vessels. Y

Another object'is to provide an appara-tus of this character which is so constructed and arranged that it may be operated either by motor or by hand; and a further object is to provide an apparatus which is capable of employing agitator devices of different sizes.

Other objects willappear hereinafter.

The invention consists in the combinations and arrangements of parts hereinafter described and claimed. Y

'Ihe invention will be best understood by reference to the accompanying drawings forming a part of this speciiication, and in which, K

Fig. 1 represents a vertical sectional view through my improved mim'ng apparatus in association with a vessel containing material to be mixed; y

F ig. 2 represents a. top plan view of the parts shown in Fg.j1; Y

Fig. 8 is a horizontal proximately on the line 8)*8 of Fig. 1; and

Fig. 4 is a vertical section taken approxiiately on the line 41-4 of Fig. 1.

The preferred form of construction as illustrated in the accompanying drawings. comprises a lid 5 having a downwardly olfsct central region 6 to provide a bearing 7 for an upright shaft 8 which extends both above and below theA lid andy is rotatably supported upon an antifriction device 9 suitably seated upon the offset portion 6 and surrounding the shaft as shown, there beingr a shoulder 1() provided on the shaft for supporting it upon the antifriction device.

Mounted uponV the. .lid is a housing 11 through the top part 12 of which the shaft 8 protrudes for the applica-tion of a hand operated crank 13. Also mounted upon the lid` is an electric motor 14 whose driving shaft 15 extends into the housing where it is provided with a driving pinion 16. In mesh with` the pinion 16 is albevel gear 17 which is loosely mounted on the shaft 8, there belsection taken apy 1926. Serial No. 112,593.

ing, in the present embodiment, a shoulder 18 provided on the shaft 8 for the operative support of said gear 17. Also loosely mounted upon the shaft Sfis a pinion 19 which is fast with the gear 17 to turn therewith; and said pinion 19 is engaged with a gear 2O loosely mounted on a stud shaft 21 ixed in the housing 11 as shown, so that said gear 20 is operatively supported upon an arm 22 of the housing. Fixed to the gear 20 and loosely turning on the stud shaft 21 is a pinion 23 which is engaged with a gear 2d fixed on the shaft 8. This gearing arrangement comprises reduction gearing for rotating the shaft 8 from the electrical motor 14k at reduced speed; and it will be observed in this connection that the shaft 8 may be rotated either by the electrical motor 14 or by the hand operated crank 18.

According to an important feature of my present invention, the lid 5 is provided with means whereby to be secured as a cover upon vessels of different transverse dimensions.

'In carrying out this feature of my invention, the lid 5 is provided with a plurality of slos 25 which extend radially inwardly into its body from its periphery 26. In the underface of the lid and more particularly in the walls defining the slots 25, grooves 27 are provided to constitute guideways for the clamping members 28 carried by screw bolts 29 arranged in the slot-s 25 and provided with nuts 30 whereby to secure the clamping Amembers in the adjusted positions desired.

Each clan'iping` member 28 is formed with a pair of depending arms 81 adapted to straddle the top edge of the vessel to which the lid is to be applied. The arms 31 carry screw bolts 82 adapted to be engaged 'with the outer and inner faces of the marginal edge of the vessel as shown, the said screw bolts being provided with heads 33 made in the form of wingnuts whereby readily to be turned. In Fig, 1, I have shown the lid clamped upon a liquid holding vessel Si; and from what has been said, taken in connection with this drawing7 it will be evident that, due to the provision of the radially adjustable clamping means, the lid may be secured upon liquid containing vessels of different transverse dimensions.

The preferred form of mixing device comprises a head bar 85 from which depends two mixing frames 36 and 87 each consisting of a pair of opposed side blades 38 which are connected at their bottom ends by -a horizontal blade 39, it being observed that the mixing'frame BY is of less size than the frame 36 and is located inwardly thereof.v

The head bar 35 is mounteduponthe shaft 8 for ready adjustment thereon, either to? Ward or from the lid 5; the means for adjustably mounting `the head bar on the` shaft consisting 1n providingthe head bar' with aV transverse aperture L1 for receiving the shaft and also 1n providing the head bar Y with a thumb screw f1 for securing` the head bar in'tne adjusted position desired. Pref-VV erably and as shown, the side blades 38`of themiX-ing frames are of diamond'shape in" cross section; Whilejthe 'bottom connecting blades I39 yare ofv triangular shape in crossV section,'it being observed that Vthe bottom blades39 are arranged so that their apeXes constitute cutting edges l2 and so that their top-upwardly inclined surfaces 43 serve,

during the rotation of thefmixer, to impel the material in-an upward direction. yThe sideblades38 of each frame preferably di-y verge from each other as they recede downwvardly from the head-bar 35.Y The bottom blades-'39 ofthe framesV 87'l and 38ar'e preferably -connected midwayv theirV lengths by a vertical blade 44 which is also of diamond shape in cross section. t is contemplated that'diiferent sizes of lmixing devices may be vinterchangeably employed in connection'.

Withthef'shaft 8 lso that the 4apparatus can be effectively used 'With vvessels of dierent sizes. f f v While have illustrated and described the preferred form of construction for carrying my invention into effect, this -is capable of variation'and modifica-tion Without departfing from the' spirit-'ofthe invention. I, therefore,V do not Wish to be limited to the precise details of the" construction set forth,V

but desire to avail myself of such variations and modifications Vas come Within the sco Je ofzthe appended claims.

I aving described .my invention what 'I 'claim as new and desire to secure by Letters `Patent is: Y

l. A mixing apparatus including; in coinbination,l a lid with a projecting rotatable shaft and means for rotating the shaft; a head bar slidably: and vertically adjustable on the shaft in relation to. said shaft; and a mixingfraine carried bysaid head bar and comprising a 'pair of vdiamond shaped Y side bladesand a triangulail bottom blade connecting theside blades, substantially as described. f

2. A mixingapparatus including; in-'combinatio-n7 -a Vlid With a'projecting rotatable shaft andmeans for rotating lthe shaft; a Y' bar and each comprising apair Vof diamond shaped side blades connected by a triangular bottom blade; one of said vframes being of less size than the other and 'located inwardly thereof, substantially as; described.

In testimony whereof I have signed'my name to this speciication Y Y JOHN M. BRINKLEY.
